This race of the Muntjac seems to be confined to the liill forests of Northern »Siarn, 

 but there it was rather common. It keeps to every kind of jungles, and females seems to 

 be more numerous tkan males. 



The skulls differ in some ways from those of the other race found in Siarn viz. Mun- 

 tiacus muntjac curvostylis Gray. The lachrymal pits are very large and the concavity 

 at the tip of the frontals is not so deep as in 31. muntjac curvostylis. The nasals are verv 

 long and the width of the palate between the last molar is considerably less than in that 

 species. The snout is very long and pointed. 



Outside Siamese territory this race has also been recorded from the Northern Shan 

 States and Central Burma. 



The general colouration is bright cinnamon rufous and the flanks are scarcely paler 

 than the back. The individual hairs are påle at their bases, which is one of the niain 

 points of difference between this species and Muntiacus muntjac grandicornis Lydekker 

 from Tenasserim, in which the general colouration is tawny ochraceous. 



Skull measurements : 



Greatest length = 203,o; condylobasal length = 192,o; basilar length = 178,o; 

 zygomatic width — 80,?; least interorbital breadth = 42,5; least postorbital breadth = 

 60,i ; length of nasals mesially = 59,6; length of frontals mesially = 79,o; breadth of 

 palate between last molar — 34,o; distance between lachrymal notch to tip of premaxil- 

 lare = 110,7; length of upper cheek-teeth = 57,o mm.

In the parts of the Siamese Malaya visited by the Expedition this race of the 

 Muntjac seemed to be rather common. Like the preceeding species it affects every kind 

 of jungles and was found as well in the mountain forests as in the jungles in the low- 

 lying country near the sea-shore. During daytime it generally keeps to the thickest parts 

 of the dense jungles and is then rather difficult to get. In the afternoon, however, it 

 generally comes down to the salt-licks to drink or to some fruit-bearing trees to eat the 

 fallen fruits, and is then easy to get. During night-time its loud barking note is often 

 heard.
